Claims.

Thisapplication is a divisional application of the parent application Serial No. 173,975, filed November 11, 1937, and is restricted to certain features of the invention disclosed in the parent application directed to improvements in card perforating machines.

This invention relates to a card controlled tab-ulating machine and particularly to improvements which adapt the machine for handling banking transactions and especially for automatic accounting of transactions involved in a savings account.

The main object of the invention disclosed herein is to devise a machine which permits the use of tabulating cards for representing the successive transactions and which represent primarily the amount of the transactions and each new balance which is computed from the tabulating card representing the previous balance and the withdrawal or deposit amount entered in the machine. Such tabulating cards may be utilized to control a tabulating machine of a well known form so that a detailed statement of the transactions may be provided.

A still further object of the invention is to provide means to punch each successive transaction card to represent other data such as the account number, the name and address of the person carrying the account, the date of each transaction, pass-book printing line selecting data, the type of transaction and other data, the purpose of which will be understood as the operation of the machine is set forth.

One of the objects of the present invention is to devise an improved means for comparing the account number data on the transaction card with the account number data on the pass-book so that the latter will receive only the transaction entries pertaining to that pass-book and the successive transaction card will be punched to represent the same account number, the deposit or withdrawal amount, pass-book line selecting data, the type of transaction and other data pertaining to the new transaction;

A still further object of the invention is to automatically duplicate on the next transaction card the data on the previous transactioncard, such as the account number data, the name and address data, etc.

As previously intimated, each new transaction card is perforated in a single column so'that this perforation may control the next differential displacement of the pass-book carriage. A further object of the invention consists in the provision of means for interpreting this data and to control means to cause the punching machine to punch the next transaction card with line selection data so that the next line on the passbook will be selected for printing operations.

Another object of the invention is the provision of means for setting up the dates and which data is printed on the pass-book and perforated on the tabulating cards.

A still further object of the invention is to provide a manually settable means for setting up the amount of the Withdrawal or deposit and which means electrically controls the selection of the punch magnets of the punching machine so that this data is represented by perforations made in the transaction card.

A still further object consists in the design of means which represents a. simplification of means previously devised to secure certain of the results attained herein, being particularly concerned with the account number comparing means, the means under control of the comparing means to determine whether the punching mechanism will operate at all to duplicate certain data, and the provision of means whereby a well known form of punching machine may be utilized in connection with the improved machine With very little modification so as to provide the perforation of a successive transaction card with a designation for selecting the next line of the related pass-book.

Other objects of the invention will be pointed out in the following description and claims and illustrated in the accompanying drawings which disclose, by way of example, the principle of the invention, and the best mode which has been contemplated of applying that principle.

Figs 18 is a section-al view of another onerevolution clutch mechanism and is takenon the line i-8--l8 of Fig. 6.

As previously explained, the improved machine is adapted to be utilized for accounting of deposits ancl withdrawals made in a bank. In order tobetter understand the operation of the machine, its operation will be given in an orderly manner commencing with the preparation of abalance card and pass-book for an initial ac count and then for subsequent deposits and withdrawals which make-up the subsequent transactions at the bank in which the account is placed.

Figure 2' is ashowing of a tabul-ating card of a well' known form and is of the type shownin the patent to C. D. Lake, lo. 772,482, dated August 12, 1930. Thetabul-ating card contains perforations invertical columns which are adapted to represent digital values and also alphabetical characters for alphabet data. Each tabulating card, representing an initial transacii tion for a new account as card It in Fig. 2 or for a subsequent transaction as by card Iii-l in Fig. 3', is divided into fields which in succession from left to right represent the account number,

the name of the depositor, the address thereof and the date. The remaining card fields include a single column in which is located one or more perforations to select the line for which recording is efiectedon the pass-book. The next card field is perforated to represent the old balance and which in the initial deposit is perforated t0 represent zero. The next card field comprises a single column designating the type of transaction, namely, a withdrawal or deposit. One of the two: card fields at the extreme right are allocated for the designation of the amount of the transaction whether it is a withdrawal or deposit and the other for the amount of the new balance.

Ihe blank card which is to indicate the opening of an account is placed in a well shown form t of key cont-rolled punching machine (Figs. 15 and 16) so that the data pertaining to the opening of an account will be punched thereon. The form of punching mechanism preferably employed in connection with the present system will be subsequently described in detail.

By the depression of the appropriate keys El (Figs. 15 and 16) the tabulating card placed in such punching mechanism will be punched to represent the account number and such numbers are obviously selected according to a serial order. Thereafter, the next card field is punched to represent the name of the depositor and in the next card field the address of such depositor. The card is also punched to represent the date of the opening of the account and the column for line selection is punched to represent 1, as shown in Fig. 2, to thereby cause the initial recording on the pass-book on the first line by means to be subsequently explained in detail. As previously stated, the field for the old balance is punched to represent zero.

The; pass-book ll comprises a card folded in the center as illustrated in Fig. 7 by a dotted line and as shown therein the name of the depositor and the account number allocated to such depositor is written on the top. The pass-book is opened as shown in Fig. '7 and is inserted in the key controlled punching machine so that the lower part thereof is punched to represent the account number which is allocated to. the depositor and: in all transactions. should. conform to the account. number punched. upon the new and with each ot the. successively selected. old balancecards I EH which are picked from the. files as successive transactions are made for: the depositors account.

The above is a description of the preparation of the. initial balance. card and. the passebook for opening of an account. Thereafter, as will now be described, the balance card is-placed in the machine shown herein and the pass-book is placed on a carriage therein so that. by the manual movement of the carriage the. latter will: be: moved to. cause a cardsensing operation so that the account number punched on the passbookmay be automatically compared column. by column: with the account number punched on the balance card. Since in the initialopening of an account there is little opportunity for lack of identity: between a pass book and the bdance card, such a comparing operation for the: initial account is not essential but as hereinafter described such identity for subsequent transactions must be preserved between the pass-book and the old balance transaction card and both should pertain to the same account.-

Card analyzing mechanism When the tabulating card 1'0 has been punched to designate data for the opening of a new account, the latter is inserted in the machine, as shown in Fig. 6', in order that the account number may be analyzed'by analyzing mechanism now to be. generally described. The analyzing mechanism for analyzing the card ii! is preferably of the type shown in and claimed in the applicationto T; E. Torkelson, Serial No. 117,282, filed December 23, 1936, and. will only be generally explainedherein and in connecfion with Figs. 6 and 13.

The assembly plate for the analyzing mechanism comprises a back plate [2 and a pair of integral side plates 13' and 14' which are provided with slots engaging. guide pins I5 carried by the side frames of the machine whereby the movement of the analyzing frame is guided. Carried by the back plate I2 is an analyzing. head which carries columns of spring contact elements Hi, there being a vertical column of contacts It. for each of the columns of the card to thereby analyze the perforations therein. Each column of contact elements It has an electrical contact with a common conducting bar ii and each contact [6' is adapted to pass through a perforation in the column and contact with a related contact point Hi There is. of course, one contact point I8 for each contact element l6 and groups of the latter are embedded in a fixed insulating member Hi. The analyzing mechanism is shown in shifted or analyzing position in Fig. 6 and obviously in the normal position there is a space between the contact elements l6 and the contact points |8 so that the card it] may be freely inserted therebetween until the lower edge of the card It rests upon a pair of card stops 25.

Connected at their ends by a pin 2| (Fig. 6) is a pair of toggle levers 22 and 23, the toggle lever 22 being connected at 24 to the analyzing frame and the toggle lever 23 is pivoted upon a fixed rod 25. Toggle lever 23 has an integral extension 26 which is connected by a pin 2'! to the core 23 of an analyzing control magnet 29. When the magnet 29 is energized, the core 28 will be attracted downwardly to the position shown in Fig. 6 thereby rocking integral extension 26 of the toggle lever 23 clockwise until the point of the toggle levers 22 and 23 as the pin 2| moves upwardly past the center of the toggle system and until the toggle lever 23 abuts an adjusting screw carried by the stationary rod 56. This position of the toggle levers 22 and 23 will be maintained by a spring 3| connected to the lever 26 so as to retain the analyzing head in analyzing position. The means for causing the movement of the analyzing head to analyzing position is under control of an operating key 32 shown in the Wiring diagram in Fig. 1b. This key is operable exterior of the machine and when depressed closes contacts 33 thereby closing the circuit to the magnet 29 through relay contacts We now closed and across a positive bus bar 34 and a negative bus bar 35. As previously, the energization of the magnet 29 causes the movement of the analyzing head and the contact points l6, associated with the columns in the card it which are perforated to represent the account, will pass through such perforations and make contact with the appropriate contact points l8 to thereby continue the closure of comparing circuits to be subsequently described.

Pass-book carriage The pass-book carriage is shown in Figs. 6, 10, and 11 and as shown therein comprises a passbook supporting plate 36 which carries lateral guide plates 3! and 38 slidable in longitudinal slots 36 (Fig. formed in side frames46, 4|. By such guiding means, the carriage may be moved within the machine. The pass-book II is inserted in an aperture 42 (Fig. 11) formed by a pair of spaced stationary guide plates 43, 44 and the card is manually pushed on the card carriage to occupy the position shown in Fig. 11.

The pass-book carriage is also provided with an analyzing mechanism for the four columns of account number data and is generally designated by 45 and is of substantially the same construction as that described in connection with the card analyzing mechanism and is so mounted upon the end of the pass-book carriage as to be correlated with the four columns of the pass-book which are punched to represent the account number. As best shown in Fig. 11, the passbook analyzing mechanism comprises four columns of contacts 46 contacting with four contact bars 4'! each common to a column of contacts. The contact bars 43 engageable by the contacts 46 through the perforations are, as shown in Fig. 9, carried by an insulating plate 46a attached to the pass-book carriage and this overhanging portion is adapted to firmly hold the pass-book upon the carriage. The spring con tact elements 46 will, in the manner previously described, pass through the perforations and make contact with the correlated contact bar 48.

When the pass-book is placed upon the carriage, by means of a finger piece 49 secured to the carriage the carriage may be moved to the left as shown in Fig. 10. Dependently carried by the pass-book carriage is a plate 56 (see Fig. 6) which carries a series of insulated contact-elements 5|, 52 and 53 (see also the wiring diagram, Fig. 1b).

Referring now to the wiring diagram (Figs. 1a

5 and 111), it will be seen that, when the carriage 56 is manually moved to the left as shown in Fig. 10, the contact element 53 will successively contact four stationary contact elements 54 and thereby extend a circuit from the positive line side 34 (Fig. 1a) through a Wire 55, relay contacts 56a, wire 51 (Fig. 1b) which is connected to the contact element 53. From the four contact elements 54 there are wire connections 58 which lead as shown in Fig. 1a to the common conducting bars 41 of the pass-book analyzing mechanism. The circuits also extend from the bars 41 by Wires 59 and normally closed relay contacts |6|Ja to the common conducting bars ll of the card analyzing mechanism.

It will be observed that, when the account number perforation in the first column of the pass-book is analyzed, the circuit will lead from the positive line side 34, wire 55, relay contacts 56a, wire 51, contact 53, the first column contact 54, wire 58, common bar 41 for the first column, the contact element 46 passing through the perforations at the 2 position, the contact bar 48, and a wire to a relay magnet 6| and to the negative line side 35. The circuit will also be extended from the bar 4'! for the first column by the wire 59, relay contacts |65a, common bar H, the contact spring element l6 of the card analyzing mechanism which passes through the perforation at the 2 position, contact point l8, and thence by a wire 62 through normally closed relay contacts IBM and to a relay magnet 64, to the negative line side 35. If there is an identity in account number perforations on the pass-book and card, related magnets 6| and 64 will be simultaneously energized so that the relay magnet 6| will open relay contacts 6|a. Relay magnet 64 when energized will open its relay contacts 64a. It will be seen, therefore, by the alternate position'of the armatures of the corresponding relay magnets 6| and 64 that a circuit described as follows will be open: from the negative line side 35, through a wire 65, a wire 66, relay contacts 6| b now closed, a wire 6! to the relay contacts 64a, which are now open, a wire 6| to a relay magnet 56, and to the positive line side by wire 55. This circuit will be open at the relay contacts 64a if the relay magnet 64 is energized simultaneously with the corresponding relay magnet 6|. The alternate circuit between Wires 66 and 8| including relay contacts 641) now closed and a wire 86 will be broken by the relay contacts 6| a. In the event that there is similarity in the perforations in each of the four corresponding columns in the card and. the pass-book, the corresponding relay magnets 6| and 64 are simultaneously energized. As the carriage is manually moved, the contact element 53 will engage the successive contact elements 54 thereby efiecting a comparison between the perforations of corresponding columns of the pass-book and the tabulating card.

In the event that there is a proper identity in the account number analyzed on both the card and the pass-book the following circuit will be made: from the positive line side 34, wire 55, relay contacts 56a, wire 51, movable contact element 53, a stationary contact element 63, to a Wire 69, a punch control magnet ll, a wire 12, wires 13 and I4 to contacts l5. As best shown in Figs. 1b and 10, the card carriage has attached thereto a ratchet toothed plate it carrying a roller I! which in the initially moved position of the pass-book carriage permits contacts 15 to close thereby extending the circuit through the contacts 15 to a wire 18 thence to contacts 79 and a wire 82 to the negative line side. As will be subsequently explained, the energization of the punch control magnet II will cause automatic punching operations to be effected by a punching machine.

In the event that one of the perforations of the corresponding columns of the card and passbook disagree, it will be seen that the normal closed position of relay contacts Ella. or E ia for non-corresponding relay magnets SI and 64 will be retained due to the fact that corresponding relay magnets SI and 64 are not energized, thereby closing the circuit across the wires $6 and 8| by either a wire 61 or a wire 30 to cause the relay magnet 56 to be energized and open its relay contacts 56a and close its relay stick contacts 56b. The closure of the latter will extend the circuits from relay magnet 56 to a wire 83 (Fig.

lb) to contact 15 now closed, wire 13, contacts 19, wire 82 to the negative line side, thereby retaining magnet 56 continuously energized.

Summarizing, therefore, a dissimilarity in perforations in corresponding columns of the card and the pass-book will cause the relay magnet 56 to be energized and its relay contacts 560. to open and the stick relay contacts E2) to close. The last named contacts will retain magnet 55 energized so that, when the column contact 53 finally makes contact with the contact point 68,

Means for determining the position of passook carriage for selection of line printing From Fig. 7 it will be observed that the passbook is provided with twenty printing lines one of which may be selected under control of a perforation in the tabulating card so as to cause the stopping of the pass-book carriage when it is manually moved to the left (Fig. to thereby correlate the selected printing line of the passbook with recording elements which will be sub-- sequently described. It will be recalled that in opening an account the first tabulating card Ill punched is punched in column 60 at the 1 index point position (see Fig. 2) so as to cause the selection of the first printing line on the pass-book. This is effected by means now to be described in detail.

It will be seen from Fig. 111 that in the movement of the pass-book carriage after the contact element 53 leaves the stationary contact point 68 the former will engage and contact with a stationary conducting strip and the movable contact element 5| will thereafter make successive contact with a series of stationary contact points 86. The series of ten contact points 86 have related wire connections 81 to the ten stationary contact points I8 of the section of the card analyzer provided for analyzing the perforation in the line selecting column. Therefore, through the movable contact element I6 passing through the perforation at the 1 position and contacting with the contact point IS a, circuit will be closed when the movable contact element 5| strikes the contact elements 861 which has a wire connection to the contact element It correlated with the 1 index point position of the line selecting column. This will cause an energization of the carriage stop solenoid 88 by a circuit now to be described. This circuit extends from the positive line side 34 (Fig. 1a.), wire 55, relay contacts 56a which are closed if there is an agreement in the account numbers of the passbook and tabulating card, wire 57 to the contact element 53 (Fig. 1b), common conducting strip 85, a wire 39 to the common bar H, the contact points It and I8 contacting through the perforation at the 1 index point position, the wire Bli, contact point 861, contact element 5|, relay contacts [32c now closed, wire iii, to the solenoid 88, and from the solenoid to the wire l3, the wire 74, contacts 15 now closed, Wire 18, contacts 19, and a wire 82 to the negative line side 35.

Since it is assumed that the 1 index point position is perforated in the line selecting column of the tabulating card, the pass-book carriage will be stopped at a predetermined position which is selected by the energization of the magnet 83. As best shown in Figs. 1b and. 10, the energization of the magnet 88 will draw within its core 92 and rock a T-shaped member 93 so as to cause a double pawl 94 having a spring connection therewith to engage upper and lower ratchet teeth 95 of the plate It. The upper and lower ratchet teeth are oppositely formed so that in coaction with the double pawl they will prevent further movement of the pass-book carriage to the left or its restoration to the right. The carriage is now held in such a position that the subsequent recording operation on the pass-book will be eifected on the first line of the pass-book as will be later explained.

It will also be clear that, if the account numbers are not in agreement, contacts 560. will be opened and the circuit to the solenoid 88 will not be completed permitting the pass-book carriage to be moved entirely within the machine and then restored by a return spring. The failure to stop the carriage during its movement and its full restoration will also be an indication to the operator that the account numbers on the tabulating card and pass-book are in disagreement.

Punc ing machine The punching machine shown herein in Figs. 15 and 16 is of a type well known in the art and is fully shown and described in the patent to F. Lee et al., No. 1,976,618, dated October 9, 193a. Only so much as is necessary to understand its coordination with the present improvements will be explained.

From Figs. 15 and 16 it will be seen that the punching machine is provided with keys 9 corresponding to those of t e patent for manual punching operations to punch the initial tabulating card. ID for opening an account.

One of the functions of the punching machine is to automatically reproduce on a blank card in the machine the data on 67 columns of the tabulating card I'U (Fig. 2) to thereby produce a duplicate card shown in Fig. 3. This card lGI comprises the first balance card if a deposit is made.

It will be recalled from Fig. lb that the punching machine control magnet H is energized to initiate punching operations so as to cause the closure of relay contacts 'IIa (Fig. 1e). At the same time relay magnet I69 (Fig. 1b), which is in parallel with relay magnet ll, will through its relay contacts I660 also be energized to thereby close its stick relay contacts Ififid, providing a stick circuit for relay magnet I66 from the positive line side 34, relay contacts 56d, relay magnet I60, wires I2, I3 and 14, contacts I5 now closed, wire I8, contacts I9, wire 82 to the negative line side 35.

Relay contacts H5611 (Fig. 10.) are now opened. so these relay contacts IEBa disconnect the part of the card analyzer shown in Fig. 1a from the wires 59, and from the magnets 64 to prevent any false circuits possible.

The punching control magnets 60 (see Fig. 1e) correspond to those in the aforementioned patent and are successively selected as the perforations in the tabulating card II] in. the columns representing the account number are analyzed.

It will be seen that the negative line side 35 is connected to a common side of the punch control magnets 60 by a wire I62 through a relay magnet I93 to be subsequently referred to.

From the magnets 65] there are twelve wire connections H34 connected to twelve corresponding digit selecting wires I660. I659, 566x and Iilfia, through normally closed relay contacts I631. The wires I 66 terminate as shown in Fig. 1e with connections to the wires I64 through the relay contacts I631 which are now closed. The digits -9 aside of acontact point or any line indicates its digital representation while X and R signify pun'ching at the 11th and 12th positions of the tabulating card, respectively. Obviously, for each analyzer section the contact element I8 which engages the related contact element I6 through the perforation in that column will select the appropriate punch control magnet 66. From the four common bars I? of the account number card analyzer (Fig. la) there are connections to four wires in a cable H3! which are connected to contact points I68 (Fig. 1e) carried by a stationary strip of a col-. umn selector. With these contact points I68 a column selector lconta-ct element I69 carried by the card carrying carriage will make successive contact therewith and. also with a common 0011-" ducting strip II 0. From the strip IN] the circuit to the positive line side to energize a selected punch control magnet 60 is through a wire con nection III, to contacts I28 now closed, relay contacts Ila now closed, contacts 81 now closed, and a wire II2 to the positive line side 34.

It is explained that due to the previous positioning of a card IiiI to the punches (Fig. 15) the carriage has skipped under control of a column skip bar (identified in Fig. 15 as column skip bar and corresponding to the bar I52 in the Patent No. 1,976,618) to the first column punching position at which time contacts I35. (Fig. 16) (which are the same as in the patent) are opened through a high part of the skip bar.

The column selector IE9 is now positioned over the first column contact of the strip so that, when relay contacts Ila are closed, punching for the first column is effected and automatically continued because the low part of the skip bar will permit contacts I35 to be retained closed.

The column selector shown at the bottom of Fig. 1e, comprising in part elements I68 and N19, is well known in the art and is fully described in the patent to G. F.'Daly et al., No. 2,016,706, dated October 8, 1935.

The means for causing the operation of the punches 5 (Fig. 15) under control of the punch magnets 66 is also well known and is fully described in the patent to Lee et al., No. 1,976,618.

After punching the first balance card IUI with the account number analyzed on the card II], successive punching operations occur to punch the alphabet data in columns 555 of the tabulating card In from the alphabet data analyzer shown in part in Fig. 10.

To this end there are suitable cable connections to the column selector from the common bars ll of the alphabet data analyzer and in this instance the bars I1 are split so that the index points 1-9, inclusive, are related to the lower part of the bar I! and index points X, R, O are related to the upper'part of the same bar I I. This is necessary in view of the punching of the perforations in code to represent alphabet data. The twelve wires Iil6 .IB69, I66 36R are also multiplied to the sets, of contacts I8 for the selection of magnets 66. Cables H3, H4 (Fig. 10) from' the alphabet analyzer are connected to lower contact points on the column selector as shown in Fig. 1c. The cables H5 and H6 (Fig. 1e) from the upper contact points It!!! of the column selector are connected to the upper parts of the bars IT, as shown. in Fig. 1c. Punching operations will thus continue automatically and where necessary two punch control magnets 6'9 are energized for code punching in a single column.

The next punching operation comprises punching in columns 56-69 of the date on which the transaction occurred and the date setting mechanism is shown in Figs. 8 and 11 and in the wiring diagram in Fig. Ic.

Columns 56 and 51 are appropriated for the punching of a number indicating the twelve months and columns 56 and 59 for the date of such month.

The ten digit selecting wires I06u!669 leading from the ten control magnets 66 are connected to ten wires II'I (Fig. 1c) and the latter are individually connected to ten commutator segments H6 formed in an arcuate insulating ring H9 (see Fig. 11).

Date setting wheels E20 settable exteriorly of the cabinet carry brushes I22 adapted to contact with the segments H8. The two date setting wheels IZtD at the right (Fig. 8) are set to represent any date from 1-31 and coact with the ten segments H8 (Fig. 10) to cause the selection of the punch control magnets 60 to cause the date punching. The month date setting wheel IEQM has a brush I22a adapted to contact with the ten segments H8 to cause the selection of the punch control magnets Mior the punching of the months by perforations at the 1-9 index point positions. At the tenth month position of the wheel I2$M the brush I22a coacts with the 0 segment I I8 and a brush I222) of the other wheel IEflM coacts with a segment I23 which has a wire connection I24 to cause the selection of the 1 punch control magnet 69. At the eleventh month position both brushes I22a and I221) contact the segment I23, and at the twelve month position the brush I22b contacts with the segment I23 and brush I22a contacts with a segment I25 having a wire connection I26 to select the 2 punch control magnet.

Against each ring I21 (Fig. 11) carrying a brush I22 bears a contact plate I3I and the four contact plates I3I have wire connections to wires in a cable I30 through normally closed relay contacts I53d. The cable I30 connects as shown in Fig. 1e to contact points of the column selector for columns 5659.

The next automatic punching operation is to punch a perforation in column 60 to represent the next line to be selected on the pass-book for recording. This is necessary because the first balance card will be used in the subsequent transaction just as the initial tabulating card was and, therefore, the next or second printing line of the pass-book must be selected. In the initial account the perforation was at the 1 index point position and under control of this perforation the first balance card IOI will be punched at the 2 index point position (see Fig. 3) by means now to be described.

When the pass-book carriage is moved to a line selecting position, a selected one of a series of relays I32 (Fig. 1c) is set up under control of the analyzer for the line selecting column. In the example assumed, for the 1 index point perforation a circuit described as follows will be completed to a relay magnet I321 (Fig. 10). From the positive line side 34 (Fig. 1a) wire 55, relay contacts 55a, wire 51 (Fig. lb) contact element 53, contact strip 85, wire 89, common bar II, contacts I6 and I8 engaging through the perforation at the "1 index point position, wire 811, to relay magnet I321 (Fig. 10) through its relay contacts I32b, and by a common wire I33 for said magnets I32 to a wire I3 which leads to the negative line side as previously described. The relay magnet I321 will close its relay contacts I32a to provide a stick circuit by a wire I 34 to the positive line side 34. Relay contacts I320 will also close and by a wire connection I 362 connected to the desired wire I962 a punch control magnet 60 will be selected for energization which will cause punching of the next higher index point position, or at the 2 index point position in the example assumed. Therefore, if an old balance card is punched from either 1 to 8, the next higher index point positions, or 2-9, will be punched on the next balance card, effected by the appropriate wire connection between the wires I06 and the wires I36.

To complete the circuit to the selected punch magnet a common conducting wire I3'I for the relay contacts I320 (Fig. 1c) is connected as shown in Fig, 1e to the lower contact point for the column selector at the 60th column.

Later there will be described the means for changing the punching from 9 to represent 10 at the line selecting column on the next balance card, etc.

Thereafter, under control of the card analyzer for columns 61-66 the punching operations continue to represent by perforations on the new balance card the old balance on the previous balance card and which for an initial account is 000000-. In view of the fact that such punching involves mechanism to be later described the specific manner in which this is accomplished will be later described. At the 67th card column position the high part of the skip bar opens contacts I35 to stop the punching operation at this card column.

Setting up amounts for withdrawal or deposit The amount which is deposited or withdrawn is set up in the machine after the punching machine has duplicated data and punched other data to represent a new balance card. When the punching operation is terminated either a deposit key I38 (Fig. lb) or a withdrawal key I39 is depressed; depending on the transaction.

If key I39 was previously depressed, a circuit to a magnet I40 is closed and held closed by the following described circuit: from the negative line side 35, wire 82, wire I4I, contacts I42 closed by key I39, relay contacts I49a, relay magnet I40, to wire 51 which leads as previously described to the positive line side 34. Relay contacts I43b are stick circuit contacts closing a stick circuit through contacts I43 opened by the key I38. Due to the previous locked up circuit of the relay magnet I40 it is necessary to depress the deposit key I38 to open the stick circuit by opening of contacts I43. Since for the example assumed the initial amount is a deposit of $50.00, the deposit key I 38 is depressed.

From Fig. 11) it will be seen that the deposit key I38 is adapted to close contacts 3!! and that the withdrawal key I39 is adapted to close contacts 3"] both of which extend the circuit from the negative line side 35 to wire 82, wire I4I through either contacts 3III or 3 through relay contacts 3I2a. to a relay magnet 3I2, thence to Wire 51, and through relay contacts 56a (Fig. 1a) wire to the positive line side 34. A stick circuit to the negative line side 35 is efiected by stick relay contacts 3I2b, relay contacts 'IIb now closed, and wires MI, and 82.

Withdrawal or amount setting means The amount setting means for entering the withdrawal or deposit amounts in the machine comprises a series of six slides I44 which as shown in Figs. 11 and 14 are manually settable exteriorly of the machine. Each slide I 44 at the left side thereof carries a single contact element I45 (Fig. 12) which is positioned for cooperation with one of a series of ten contact points I45 dependent upon the digit positioning of the slide I44. Each slide I44 is manually drawn towards the operator against the action of a spring I 41 and the differential position of the slide is maintained by a retrograde preventing pawl I48 (Fig. 11) engaging a ratchet tooth I49 of the settable slide I44. If an error has been made in setting the slide, a projecting portion I59 of the retrograde preventing pawl I48 is manually moved to disengage the pawl from the ratchet teeth I49 whereupon the slide may be reset to the desired position. If any digit of the amount entered in the machine should represent Zero, the slide is left at the normal position but for other digits the slides are moved toward the operator to selected digit representing positions which may be indicated to the operator by means of an index plate adjacent the slides.

Since the initial deposit is assumed to be $50.00 the slide for the tens of dollars order is set to the 5 digit representing position. After the amounts have been set up as just described, the operating key 32 (Fig. 1b) is again depressed which will close the circuit from the positive line side 34 through relay contacts Ilia now closed, contacts 33 closed by the operating key 32, and

thence by a wire I to the punching machine control magnet II and the circuit then extends by the wire I2, I3, I4, contacts I5 and I9 and wire 82 to the negative line side 35. As previously stated, the energization of the relay magnet M will close its relay contacts Ila shown in Fig. 16 to thereby cause as previously stated the automatic operation of the punching machine so as to now punch on the new balance card certain data in columns 67 to I9.

Operation of punching machine continued When the operation of the punching machine is resumed, the indication of the type of transaction is punched upon the new balance card in column 5'! and by the following described means and such means is operative only if the amount entered is a withdrawal.

Since in the example assumed the first transaction is a deposit, no punching will be efiected in column 67 and since no punching control. magnet 613 will be energized, it is, of course, necessary to provide additional mechanism so as to cause the automatic spacing of the carriage to the next column punching position. This arrangement is also effective in alphabet punching where certain columns are not punched. Such an arrangement is well known to those skilled in the art and is fully shown and described in the patent to W. F. Gutgesell, No.

1,939,049 and for this reason is only generally described herein.

In this instance, the following described circuit will be closed: from the positive line side 34 (Fig. 16), wire IIZ, contacts 81 now closed, relay y contacts H a now closed, contacts I28 now closed, wire I52 to a relay magnet I53 and thence to relay contacts I 03d which are now closed because relay magnet I93 which is in series circuit with the punch control magnet circuits is not energized and thence by a wire I54 to the negative line side 35. The energization of the relay magnet I53 will cause the closure of relay contacts I530, thereby causing the punch magnet I55 to be connected across the positive and negative line sides and therefore energize in the same manner as it is energized by the circuit connections described in the aforementioned patent to F. Lee at al., No. 1,976,618. It is pointed out that the punch magnet designated by reference numeral I55 herein corresponds to the punching magnet in the last mentioned patent and designated therein by reference numeral 49.

By the above described mechanism the carriage will be moved to the extent of a single column so that the amount of the transaction may next be automatically punched in columns 68 to f3 by the following described mechanism.

There is shown diagrammatically in Fig. 1d the electrical connections for causing the selection of the punch control magnets Gil under control of the amount setting slides I44 but only for three orders thereof in view of the duplicate arrangement for the six denominational orders. Taking into consideration the hundreds of thousands order, which is the first order to be punched, it will be seen that connected to the ten wires Ill6olfi69 which are connected to the punch control magnets 60 for punching at the index point positions zero to nine inclusive, there is a cable connection to such wires and such cable is designated by reference numeral 556 (see Fig. 111). These ten wires I51 in the cable I56 as shown in Fig. 1d are connected to the series of ten stationary contact points I46. The movable contact point I correlated therewith has a wire connection I58 to a wire I59 through closed relay contacts I 63 The wire I59 leads as shown in Fig. 1e to a contact point of the column selector appropriated for the 68th column position and the particular control magnet 60 which will be selected for energization will, of course, be dependent upon the diiferential position of the slide I44 and the corresponding correlation of the movable contact point I45 with one of the stationary contact points I45. Thereafter, the carriage is stepped step by step and the digit amounts set under control of the remaining slides I 44 are read out by the column selector as the carriage moves step by step.

At the termination of such card punching operations, columns 68 to I3 will be punched to represent the amount of the transaction and in the example assumed only the slide I 44 of the tens of dollars order will cause punching of "5 and the number punched will be indicated as Means for punching the new balance card to indicate a withdrawal if the transaction should be a withdrawal tacts I400. From the column selector contact for the 67th position, there is a wire connection I52 (see Fig. 1e) which is connected as shown in Fig. 1b to normally closed relay contacts 5311. From the relay contacts I63a there is a wire connection to the relay contacts I400 and from the last mentioned contacts there is a wire connection I64 to a wire Ill6x which leads to the punching control magnet 600 for causing the punching at the X index point position. Therefore, if the entry should be a withdrawal the card will be punched in the 67th column to indicate this fact on the new balance card.

Punching of new balance After columns 68'I3 have been punched to represent the deposit or withdrawal amount, there is a selectionv of punch control magnets 6!! to automatically punch the new balance and is dependent upon the old balance punched on the card analyzed and the setting of the control slides I44 to represent the deposit or withdrawal. This joint cooperation involves a number of circuits not shown herein as it forms no part of the present invention and is fully disclosed in the parent application. The punching of a new balance is shown in Fig. 3 in columns I4--'I9 and thereafter the punch carriage skips to column 80.

In the present example there is no punching in the th column and the carriage is automatically escaped to this column and thereafter, by carriage controlled means fully shown in the patent to Lee et al., No. 1,976,618, contacts 9I in Fig. 1e will be .closed. This will cause the energization of the relay I91 and the closure of its relay contacts I98 and the energization of the ejection magnet I99. This causes the operation of the ejector 201 (Fig. 15) to eject the punched card whereupon contacts ZIII will be closed to cause the energization of the clutch control magnet I15 (see Figs. 15 and 16) Which by means shown in said patent will cause a new card to be fed to the punches and the restoration of the card carriage to the first column position. The numerals I15, I9I, I91, I98, I99, 2IlI herein identify the same
